M4 heads

The KEOFITT® ™ M4 sampling valve is a downscaled version of the W9 valve, offering the same quality and features for various applications. 
It is the smallest sampling valve of our Classic series and is designed for the sampling of low viscosity products in the range of 1-100 cP with particles less than 1.5 mm in diameter. 
Sampling more viscous liquids is possible, it may just take longer (depending on the process pressure). 
M4 valves are widely used in the pharmaceutical, brewery, beverage and dairy industry, to sample products like:

Purified Water*Milk*Filtered Beer 

Besides the selection of the Valve Body and the Valve Head there are three different membrane materials to choose from: Silicone, EPDM and PTFE.
Accessories include caps, adapters, PTFE tubing and more.
